IMPROVEMENT IN SAW COT'I'ONGFIN The Schedule refen'e to in these LettersPatent and making part of *he same.

To all whom 'it ana/y concern:

Be it known that I, XVILLIAM SU'rToN, of lVashington, in the county oflVilkes, and State of Georgia, have invented a new and improved SawCotton-Gin; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable those skilled in theart to make and use the same, reference being had to the accompanyingdra-wings, formingr part of this specification.

This inventiou relats to a new and useful improvement in theconstruction of hoppers for saw cottongins, whereby the cotton fed tothe machine .is acted upon equally throughout the entire gang of saws.

In the accompanying slieet of drawings- Figure 1 is a front view of myinvention.

Figure 2, a plan or top view of the same.

Figure, a transverse vertical section of the same, taken in the line a;x, fig. 1.

Similar letters of reference indicate corresponding parts.

A represents the hopper of a saw cotton-gin, B, the

, a fort-y-saw gin, the front of the hopper, c c, will be from two and ahalf to four inches narrower than its rear part, cl d, which adjoins thebody of the gin.

The proportions of hoppers will vary with size of gins. This is shownclearly in fig. 2, and in consequen'ce of the wid-th of the hopper notbeing uniform, the roll of cotton within the hopper is, when the gin isin operation, constantly shifting its position, so that fresh surfacesare constantly presented to the sa-ws, and the cotton more rapidlyginned than usual, and the fibre not injured or cut.

The roll of cotton is also kept higher up in the hopper than usual,which admits of a tree discharge of the seed, much more so than usual,and the saws opera-te with less friction, as the roll of cotton doesnotextend down so deep upon them.

In cotton-gins as heretotbre constructed, the sides have been madestraight, or pa 'allel with the face of lthe saws. rJ'his constructionis objectionable, from the fact that the spa-cos between the outcr fmyes of the outer saws and the sides of the hopper are uniform, and verylittle if any cotton can find its way into them, because of the frictionproduced by' its contact with the sides of the hopper. As a result ofthis construction, the outcr saws of the gang do very little if anywork.

By giving obliquity to the sides of the hopper, as lpropose, thedistance between the upper edges of the saws'and the sides of the hopperis greater than the distance between the lower edges of the saws and thehoppcr, and then-.torc the cotton extending over the outer saws isreadily acted upon and drawn downward.

The bars (I of the breast O are eurved, as shown in flg. 3, so as toadniit of a comparatively large number of saw-Teeth cxtending throughthe breast, but not so much of their snrfaces or plates; for instance,the distance from e to c is about three inches greater than usual, whilefrom f to fit is somcn-'hat less. (See tig-3.)

This change in the rclativc positions of the saws and breast also servesto reta-in the roll of cotton in an elcvated state in the hoppcr, and tofacilitate the operation of ginning in au eminent degree.

I claiin as new, and desire to secure b y Letters Patent- The hopper A,constructed as described, with its sides inclined, for the purpose ofsupplying the cotton to all the saws cqnally, as herein shown anddescribed.
